How do I handle parse and fatal errors?

Question

I wrote a custom error handler for my site and I'm aware that PHP doesn't allow handling of parse and fatal errors. Is there something I can do to make it handle these errors? I don't want them being outputted to the user (but I want to use my error handler for them).

Thanks!

If it can't parse your script, it won't be able to parse your custom error handler.

You should have display_errors off in your php.ini and also set error_reporting to none when your site is in production.

Also, I believe set_error_handler() can handle fatal errors.

^ What he said, there are good reasons that your script fails on parse errors, it simply does not know what to do

Was afraid of that. Oh well. And no, I already had set_error_handler() on it and it didn't work.

As at PHP 7.4.10, set_error_handler() does not still handle fatal errors; just set display_error to off, this works.

You could try register_shutdown_function. If there is an error (even parse one) in one of files you have included/required this function will still be called.

Though you won't be able to use debug_backtrace because shutdown function will be called outside of your error, you could try to use error_get_last to get some information about the error.
